A coin cell battery is used as a backup power supply to maintain the settings for the internal clock. Please
note that battery power will be consumed even if the Label Printer is not in use.
1. Make sure that the Label Printer is turned Off.
Hold the Label Printer by the front, and firmly
lift the DK Roll Compartment Cover to open it.
2. Pull out the insulation seal on the coin battery.
IMPORTANT
• Using a coin or similar object, slowly turn the coin cell battery cover in the direction of the arrow on the
battery cover until it stops, and then remove the coin cell battery cover.
Do not turn the coin cell battery cover past the unlock position, or you may damage it.
• Re-install the coin cell battery cover, using a coin or similar object to slowly turn the coin cell battery cover
in the opposite direction of the arrow cover until it locks into place.
Be sure to insert the new battery with the + and – sides facing the correct direction.
CAUTION
• Remove the battery if you do not intend to use the Label Printer for an extended period of time.
• Dispose of the battery at an appropriate collection point, not in the general waste stream. Be sure to
observe all applicable federal, state, and local regulations.
• When storing or discarding a battery, wrap it with cellophane tape to prevent it from short-circuiting.
